CIRCULAR-KNITTING MACHINE.

Specification of Letters Patent.

Application filed October 7, 1812. Serial No. 724,376.

7 To all whom it may concern."

Be it known that l, FRANK B. WILDMAN, a citizen of the United States,residing at Norristown, Pennsylvania, have invented certhe point ofknitting may be of very small diameter, while at the same time the cambox will be of suflicient diameter to rovide a satisfactory cam race'tooperate-t e needles. I a

The invention consists in the features of construction and arrangementand combinetion of parts hereinafter described and pa ticularly definedby the appended claims.

The accompanying drawing represents a.

central vertical sectional view through a ma-' chine embodying theinvention.

lln this drawing, 1 represents the needle cylinder, which is of taperedform, and

which extends a considerable distance above the cam box 2, which carriesthe cam pieces forming the cam race 3. The tapered cylinder is groovedtoreceive the needles, as in ordinary practice, and the butts of theseneedles, as in ordinary practice, enter the cam race 3. The cams arearran d in cylindrical form, as shown, but owing to t e slight taper ofthe needle cylinder the needles, in their up anddown movement, traversea path only slightly inclined to the interior of the cam cylinder sothat in their up and down movement the butts of the needlesmaintain-engagement with the cam race. in o'rder to get the needlecylinder at the knitting point of the required small diameter, the saidcylinder, as above stated, is extended a considerable distance above By.arrangin the cams in cylindrical form and by'emp oying a cylinder ofelongated tapered form, the diameter of the parts at the needle cams maybe considerable as compared with the diameter of the needle cylinder atthe knitting point, andthe room thus provided will enable a satisfactorycam race to be formed, as shown, and the needles will project into theearn race a suflicient distance for proper they lie in a circle of muchlarger diameter,

making it possible to employ a cam cylinder of a considerable size.

I claim as my invention l. A knitting machine consisting of an elongatedneedle bed of conical form, with its taper upward and a cam boxsurrounding the, lower larger diameter portion of the taper cylinder,said cam box having its cams arranged in plain cylindrical form, theneedles traversing a path but of parallel with the cam surface, andinclining toward the center of the plain cylinder, substantially asdescribed.

2. A knitting machine consisting of an elongated needle bed of conicalform with its taper upward, a cam box surrounding the lower largerdiameter portion of the conical needle bed, and a loose ring surroundinthe conical needle bed to hold the needles in the grooves thereof,substantially as described.

In testimony whereof, I a'liix my signature in presence of twowitnesses.

l RANK B, WILDMAN.
